Math History
Far more interesting than one might first expect, the history of mathematics is filled with bitter rivalries, political machinations, and incredible innovations by some of the most amazing minds in history. Post all questions concerning individual mathematicians, the development of mathematical theories, and the sociological impact that resulted into this category.

What is the longest Babylonian number between 500 and 1000?
Instead of or powers of 10, the Babylobians used powers of 60. So Babylonian 10 is decimal 60, and Babylonian 100 is decimal 3600. Decimal 1000 is 16x60 +40 =Babylonian (16)(40)
Who are some famous mathematicians?
Peano, Fibonacci, Gauss, Newton, Galileo (mostly physics), Euler, Da Vinci, Pythagoras, Euclid, Bernoulli, Archimedes, Descartes.
How was 'pi ' discovered in the first place?
You can thank the Greeks and their obsession with Geometry for this one. They found when you divided the circumference of a circle by its area I think you get 3.141...... or pi. Actually the ratio Pi is obtained by dividing the circumference of any circle by the length of the diameter. There is also some evidence which possibly indicates that this ratio (Pi) was known to the ancient Egyptians ca 2500 b.c.e.
What are some prime numbers below 30?
2, 3, 5, 7, 11, 13, 17, 19, 23, and 29 are all of the prime numbers below 30.
Yes, that is biased. Scent A is described with positive adjectives, while Scent B is described with neutral to negative adjectives.
Can you get tutoring for math on a free online tutoring site?
There are not many places that you can go to online and have a personal tutor without paying because most people do not just help others for free. There are websites that give advice for teaching students or helping them to study.
Who invented negative numbers?
One source says that a Chinese text (Nine Chapters in the Mathematical Arts) from around 200 BC used red rods for positive numbers and black for negative. So the "inventor" must be older than that. European texts up until the Renaissance considered negative numbers as absurd.
Here's a site to help you it talks about what math is and whether or not it was invented or discovered and who actually did.

Is there a special name for zero?
No, its name is zero. It is occasionally referred to as cypher, naught, nil and so forth but those names are not common.
No, this is far from the truth. I am one of those people working in a math related field.

When did mathmaticians begin using the greek letter TT?
William Jones introduced the Greek character for pi in 1707. It was the initial letter in Greek for the word perimeter. Previously mathematicians wrote perimeter/diameter to express pi.

John Venn's life of development?
John Venn is most famous for his development of diagrams, later named after him, that depict relationships between sets. Although Gottfried Wilhelm von Liebniz and Leonhard Eulerhad used similar diagrams, Venn's were considered more descriptive and easier to understand. He also helped to develop George Boole's system of mathematical logic.
Venn was born in Hull, England on August 4, 1834, a descendant of a long line of Church of England evangelicals. He received his early education at two schools in London, at Highgate and Islington, but historical records indicate that either he was so poor a student or the schools were so incompetent that he was ill prepared for college. Nevertheless, he entered Gonville and Caius College at Cambridge in 1853 and earned a degree in mathematics there in 1857. The school made him a fellow upon graduation--he would retain that status for the rest of his life.
Becoming a priest in 1859, Venn went to work as a curate in the town of Mortlake. However, by 1862 he was back in the world of academia with a job at Cambridge University as a lecturer in moral science. His courses' main topics were probability theoryand logic. It was at this point that Venn began developing Boole's mathematical logic, using what would become known as Venn diagrams to do so.
A Venn diagram is a pictorial representation of the relationships among sets. There is an outer rectangle that stands for the universal set, within which are circles or ellipses representing subsets of the universal set. For instance, Venn called three circles (R, S, and T) subsets of set U. The intersections of these circles and their complements split set U into eight nonoverlapping areas, the unions of which produced 256 distinct Boolean combinations of sets R, S, and T.
In 1866 Venn wrote The Logic of Chance, which had major influence on the evolution of the theory of statistics and developed an aspect of probability theory called frequency theory. Meanwhile, he was becoming dissatisfied with the Anglican Church, which he decided to leave in 1870. Afterward, although Venn continued to be a devout church-goer, he dedicated himself mainly to his academic career.
Venn published Symbolic Logic, an attempt to correct and interpret Boole's work, in 1881. His Principles of Empirical Logic came out in 1889, but critics largely agreed that the first work was Venn's most original. Meanwhile, Venn had become enamored of history and had written one for his alma mater in 1897. More impressive, however, was his compilation (with his son) of a history of Cambridge University. An enormous undertaking, the first of two volumes appeared in 1922.
Aside from his academic endeavors, Venn also enjoyed building machines. His talent for such extended to a device that bowled balls for cricket; the machine was so effective that the top players of an Australian team could not even make contact with the balls during a trial run in 1909. Venn died in Cambridge, England in 1923
How did Euclid find the greatest common factor?
If the two numbers are the same then the GCF is the common value. Otherwise:
- find the difference between the larger number and the smaller number.
- replace the larger of the two numbers by this difference.
- if the two numbers are the same then that is the GCF, but if not go back to step 1.
Euclidean Algorithm
It is not necessary to actually list the factors of all numbers to get the GCF for only two numbers. You can use the Euclidean algorithm.
(1) Divide the larger number by the smaller one.
(2) If there is no remainder, the GCF is the same as the smaller number.
(3) Repeat step 1 with the smaller number and the remainder.
Example:
GCF of 51 and 85.
85/51 = 1 R 34
51/34 = 1 R 17
34/17 = 2 R 0<== By step 2, we are done. Our answer is 17.
Lets try one that doesn't reduce -- GCF(17,39)
39/17 = 2 R 5
17/5 = 3 R 2
5/2 = 2 R 1
2/1 = 2 R 0, so our answer, the GCF, is 1.
